Dear Friends,
	Since I have a lot of dummies in my regression, I always get the error message like "1 obs completely determined, standard error questionable".  So I want to see the sumerization of the data set the regression use.  
e.g.
reg y x1 x2
There are some missing value in y, x1 and x2.
Want to sum	the data set which reg use after regression.
                                                       
Warm regards,
Maoyong
